Simplifier: Constant fold invald tagToEnum# calls to bottom expr.
When applying tagToEnum# to a out-of-range value it's best to simply
constant fold it to a bottom expression. That potentially allows more
dead code elimination and makes debugging easier.

ghci: Use loadInterfaceForModule rather than loadSrcInterface in mkTopLevEnv
loadSrcInterface takes a user given `ModuleName` and resolves it to the
module which needs to be loaded (taking into account module
renaming/visibility etc).
loadInterfaceForModule takes a specific module and loads it.
The modules in `ImpDeclSpec` have already been resolved to the actual
module to get the information from during renaming. Therefore we just
need to fetch the precise interface from disk (and not attempt to rename
it again).

RV64: Introduce J instruction (non-local jumps) and don't deallocate stack slots for J_TBL (#25738)
J_TBL result in local jumps, there should not deallocate stack slots
(see Note [extra spill slots].)
J is for non-local jumps, these may need to deallocate stack slots.

Add `UnitId` to `EvalBreakpoint`
The `EvalBreakpoint` is used to communicate that a breakpoint was
encountered during code evaluation.
This `EvalBreakpoint` needs to be converted to an `InternalBreakpointId`
which stores a `Module` to uniquely find the correct `Module` in the
Home Package Table.
The `EvalBreakpoint` used to store only a `ModuleName` which is then
converted to a `Module` based on the currently active home unit.
This is incorrect in the face of multiple home units, the break point
could be in an entirely other home unit!
To fix this, we additionally store the `UnitId` of the `Module` in
`EvalBreakpoint` to later reconstruct the correct `Module`
All of the changes are the consequence of extending `EvalBreakpoint`
with the additional `ShortByteString` of the `UnitId`.
For performance reasons, we store the `ShortByteString` backing the
`UnitId` directly, avoiding marshalling overhead.

compiler: Ensure that Panic.Plain.assertPanic' provides callstack
In 36cddd2ce1a3bc62ea8a1307d8bc6006d54109cf @alt-romes removed CallStack
output from `GHC.Utils.Panic.Plain.assertPanic'`. While this output is
redundant due to the exception backtrace proposal, we may be
bootstrapping with a compiler which does not yet include this machinery.
Reintroduce the output for now.
Fixes #25898.
